EFFECT OF HEAT TREATMENT ON HYDROGEN SOLUBILITY IN Zr-2.5Nb ALLOY
Anales (Asociación Física Argentina), 2022 We have studied the hydrogen terminal solid solubility (TSS) on Zr-2.5Nb. The samples were aged at 470◦C for 10h, plus a hydrogen gaseous charge followed by a homogenization treatment at 470◦C - 6 h in order of distributing the hydrogen throughout the ...

Mechanical Properties Degradation at Room Temperature in ZRY-4 by Hydrogen Brittleness
Materials Research, 2002 A hot rolled Zircaloy-4 alloy, annealed with a final cold rolling, presenting rounded grains, was studied. Hydrogen cathodic charge with a homogenization heat treatment was used to pre-charge the specimens with different hydrogen contents.

Assembly and Redox-Rich Hydride Chemistry of an Asymmetric Mo2S2 Platform
Molecules, 2020 Although molybdenum sulfide materials show promise as electrocatalysts for proton reduction, the hydrido species proposed as intermediates remain poorly characterized. We report herein the synthesis, reactions and spectroscopic properties of a molybdenum-

Multimetallic Permethylpentalene Hydride Complexes
Inorganic Chemistry, 2022 The synthesis and characterization of group 4 permethylpentalene (Pn* = C8Me6) hydride complexes are explored; in all cases, multimetallic hydride clusters were obtained. Group 4 lithium metal hydride clusters were obtained when reacting the metal dihalides with hydride transfer reagents such as LiAlH4, and these species featured an unusual hexagonal ...
